Overview
Community orientation
The Audi 100 C4 (1990–1994) is modelled here with its 2.0-litre 8v four (EA827), as sedan and Avant, front- or quattro all-wheel drive. The generation's real V6 (a 12-valve SOHC unit, distinct from the later 30-valve V6) and 2.5 TDI inline-five are not yet in the shared engine registry, so they are not modelled — a coverage gap, not a claim that they didn't exist. It authors no problems of its own: through the shared engine graph, the community patterns owned by another Audi corpus for the 8v family resolve onto this generation's configurations. This is an editorial catalogue summary, not a reliability rating.

Pre-purchase checklist
Cold start

- ☐Scan stored DTCs and check live fuel/ignition/boost data before the test drive
